Time for a new battery?
« on: April 08, 2019, 04:23:09 pm »
I was out on vacation for 5 weeks. When I got back my battery didn't have the power to start the bike (the electronics would turn on). Since I don't have a garage, couldn't keep a battery tender attached). I took it out and used my jr battery tender (0.75A) on it. It went from red to green within 4 hours. Am I looking at a battery close to dying?

Any recommendations for non-litium ones? Some people have suggested Mighty Max.

Need details. How long had it been sitting. What's the weather like where you are? How often do you ride? How old is the battery?  Etc.

I live in Los Angeles. Its the original battery that came with the bike (2014 R-spec). I didn't ride it much for the winter (nov-jan). If not usually put around 84 miles on it on a weekly basis.

It was sitting for 5 week's while I was away.

I have no mods.

I bet once you top up the battery, it will be fine.  But that little riding may require a charge more and then. Ymmv.

Thank you for the response

What concerned me was the fact that the battery charged in less than 4 hours with a 0.74A trickle charger

Test the battery with a DMM. If it drops below 9.6 volts while trying to start the engine then it needs to be replaced. Since itís the original battery I bet itís toast, especially if it wasnít kept on a tender.

I just replaced mine the other day - found a Yuasa YTZ14S on eBay for $130 shipped.

I pull the battery in the winter, put it on a tender when it's in storage. 2014 R-Spec too. Original battery. Contemplating getting a new battery, because, why not. No problems even after it went down enough to not start the bike 2-3 times. Ride it regularly from spring through late fall, then as stated above, tender in the winter.

Assuming you're going to be riding more frequently now I'd bet the battery will be fine, but you'll definitely want to keep an eye on the charge.  I have this thing permanently attached to my battery (I've been plagued by rectifier issues on my previous bikes so I'm paranoid):

Tried starting the bike today (charged Friday) and the battery was low. Time for a new battery. Thank you for all the responses.

Any recommendations on non lithium batteries?

If for some reason I don't go with a lithium i will replace mine with the YUASA battery the bike came with.  I'm going on 6 years with the same battery.

STOCK Battery suggested - Yuasa YTZ14S , it costs $139 on Ebay NEW (includes shipping)
KOSO speedometer kept the Mileage and Gear set-up ONLY CLOCK needed reprogrammed
I switched the battery in 22 minutes
HISTORY - i bought my bike, 2nd owner (2016 BOLT) and in Feb 20202 i bought a NEW Battery with higher CCA number
BUT , when it got cold , the VOLTS dropped immediately and my BOLT would not crank over fully and START
SO - i just purchased another NEW Battery - the STOCK battery - on first 3 start ups, it starts IMMEDIATELY, QUICKLY
i always put BOLT on trickle charger in my garage AFTER Every ride
